Job Description
Senior macOS Engineer owning native endpoint security agents for Check Point’s enterprise AI platform. Building TLS interception, proxy controls, and data-loss protections across managed Macs.
Responsibilities:
- Own the macOS agent end-to-end
- Architect and maintain privileged system services, inter-process communication, and robust self-updating mechanisms across non-administrated endpoints
- Implement TLS interception and certificate trust chains on macOS
- Resolve system proxy configuration conflicts alongside endpoint security tools, VPNs, and cloud proxies
- Build native interception capabilities for AI developer tools to monitor and apply data-loss policies
- Enforce fail-open architecture so local failures do not degrade network connectivity or access to corporate assets
- Analyze customer logs and clean-state Mac reproductions to identify root causes and ship permanent fixes
- Own product fixes for conflicts with other endpoint security products
- Serve as principal technical authority for macOS engineering decisions across R&D
Requirements:
- 5+ years of systems-level software development
- 3+ years delivering production macOS software using Swift and Objective-C
- Deep expertise in macOS platform internals, including launchd, XPC, code signing, notarization, packaging, privileged operations, and debugging complex runtime behavior
- Solid grounding in networking fundamentals, including system proxies, TLS, certificate trust, and application-to-internet connections
- Hands-on proficiency with modern AI development tools such as Claude Code or Cursor
- Critical, verification-first approach to AI-generated code
- Clear technical communication skills
- Experience resolving critical technical issues alongside field engineers and enterprise IT teams
- A CS degree or equivalent practical engineering background
Benefits:
- Building a native macOS platform rather than maintaining a ported Windows client
- Full technical ownership over privileged services, trust chains, proxy configuration, and network components
- Engineering culture enforcing strict "fail open" reliability
- Root-cause product fixes rather than customer-side exclusions or temporary workarounds
